A massive connectivity outage occurred across Microsoft's email, Office, and artificial intelligence services, causing significant inconvenience for users worldwide. According to Reuters and major foreign news outlets on the 12th local time, the outage centered on the Outlook email service and spread to key business and AI software, including Microsoft 365, Teams, and Copilot.

According to data from online service outage monitoring site Downdetector, more than 120,000 Outlook users in the United States alone reported connection errors. Incidents of inaccessible email accounts and delays in sending and receiving messages occurred consecutively, with tens of thousands of damage reports also filed for Microsoft 365, Teams, and Copilot services. The issue began in the United States and simultaneously affected users in various regions around the world, including the United Kingdom. In the UK as well, outage reports related to the Microsoft product line surged during evening hours, causing work disruptions.

Microsoft stated in an official statement that increased infrastructure load was the cause of the incident. The company explained that rather than a general surge in external traffic, some servers unexpectedly became unavailable, concentrating traffic and computational burden on the remaining infrastructure and triggering cascading connection errors. The Teams outage in North America was resolved first, but connectivity issues with Microsoft 365 and other services continued in other regions worldwide.

Immediately after the outage occurred, Microsoft halted all deployment operations and swiftly began traffic redistribution and infrastructure load balancing. Additionally, the company is conducting configuration change tests to resolve server errors that fail automatic status checks, continuing rapid recovery efforts. As global companies and office workers faced significant confusion due to the simultaneous paralysis of major business and communication platforms, the potential risks inherent in massive cloud and AI infrastructure and the need to enhance structural stability have once again emerged as a major global issue amid accelerating digital transformation.
